The focal metallic cartilage resurfacing is a surgical method that offers an appropriate step between the biological techniques and arthroplasty in middle-aged patients with full-thickness cartilage defects. The advantages of this technique are that it addresses the defect, respects healthy tissues and provides stability and contoured surface similar to a full arthroplasty. A systematic review was conducted according to Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines. Two reviewers (MM and DC) independently conducted the search using the MEDLINE/PubMed database and the Cochrane Database of Systematic Reviews (CDSR). These databases were searched for the terms hemicap knee implant and unicap knee implant and knee focal metallic implant. From the initial 21 studies that were evaluated, 10 were eligible for analysis. Considering both the HemiCAP focal implant and the HemiCap® Wave patellofemoral prosthesis, we found a lack of mid- to long-term clinical outcomes in well-designed prospective clinical studies. No Level I or II studies were found, while the limited number of patients who were included undermines the overall clinical results of these studies. The progression of osteoarthritis, the persisting pain and the subsequent high revision or failure rates in the limited available studies with long-term follow-up, seem to be the major drawbacks of these partial resurfacing techniques. Utilization of partial resurfacing for femoral or patellofemoral compartments results in good short-term outcome for middle-aged patients as a step between biological technique and total knee arthroplasty. The surgeon should be cognizant and also notify the patient of the high failure rates that are reported in the literature in mid- to longterm follow-up and ultimately, the decision to perform partial resurfacing should be taken by both the patient and the orthopedic surgeon.

Objective: The objective of this prospective audit was to determine the long term outcome of patients diagnosed with chronic migraine who were treated with onabotulinumtoxinA for the prevention of chronic migraine. Background: While long term and real-world studies have confirmed the safety and efficacy of onabotulinumtoxinA in CM, there remains limited information from large patient numbers on the number of cycles and duration of onabotulinumtoxinA needed to successfully convert chronic migraine to episodic migraine, development of resistance to treatment and sustainability of response after stopping treatment. Methods: A total of 655 adult patients diagnosed with chronic migraine who received onabotulinumtoxinA at the Hull Migraine Clinic were followed up prospectively for a minimum of 2 years. OnabotulinumtoxinA was delivered as per the PREEMPT study protocol and patients were asked to keep a headache diary for at least 30 days prior to and continuously after receiving onabotulinumtoxinA. The primary outcome assessed in this prospective real-world audit was either the number of patients who achieved a ≥50% reduction in headache days or migraine days or an increment in crystal clear days twice that of baseline in a 30-day period. Patients were also assessed for analgesic medication overuse. Results: Treatment data were available for 655 patients who commenced treatment between July 2010 and October 2016 and followed for at least 2 years (24–70 months), with the last follow-up taking place in September 2018. Of the 655 patients, 380 patients responded to treatment after two cycles and went on to receive the third cycle. Of these, 152 patients were still on active treatment at 2 years. A further 61 patients had relapsed and were on treatment at 2 years. Of the 228 patients who stopped treatment, 112 were successfully converted to episodic migraine and showed a sustained response, 28 reverted to chronic migraine after the initial response despite continuing treatment (developed resistance), 14 were lost to follow up and 61 patients after achieving remission relapsed after a mean of 9 months (range 4–24 months) and recommenced treatment with onabotulinumtoxinA. Conclusion: After a minimum of 2 years, 29.4% of patients with chronic migraine who initially responded to treatment were successfully converted to episodic migraine and maintained a sustained response. Forty percent of the initial cohort of responders continued therapy with onabotulinumtoxinA to manage their chronic migraine.

OBJECTIVEDue to their distinct location, suprasellar arachnoid cysts are known to cause a wide variety of problems, such as hydrocephalus, endocrine symptoms, and visual abnormalities. The long-term outcome of these cysts has not been elucidated. To find out the long-term outcome of suprasellar arachnoid cysts, a retrospective review of the patients was performed. The neurological and endocrine symptoms were thoroughly reviewed.METHODSForty-five patients with suprasellar arachnoid cysts, with an average follow-up duration of 9.7 years, were enrolled in the study. A comprehensive review was performed of the results of follow-up regarding not only neurological symptoms but also endocrine status. The outcomes of 8 patients who did not undergo operations and were asymptomatic or had symptoms unrelated to the cyst were included in the series.RESULTSSurgery was most effective for the symptoms related to hydrocephalus (improvement in 32 of 32), but endocrine symptoms persisted after surgery (4 of 4) and required further medical management. More surprisingly, a fairly large number of patients (14 of 40; 1 was excluded because no pre- or postoperative endocrine evaluation was available) who had not shown endocrine symptoms at the time of the initial diagnosis and treatment later developed endocrine abnormalities such as precocious puberty and growth hormone deficiency. The patients with endocrine symptoms detected during the follow-up included those in both the operated (n = 12 of 32) and nonoperated (n = 2 of 8) groups who had been stable during follow-up since the initial diagnosis.CONCLUSIONSThis study implies that patients with suprasellar arachnoid cysts can develop late endocrine problems during follow-up, even if other symptoms related to the cyst have been successfully treated. Hence, patients with these cysts need long-term follow-up for not only neurological symptoms but also endocrine abnormalities.

Background: We investigated the long-term clinical results of percutaneous transluminal angioplasty (PTA) in patients with peripheral arterial occlusive disease (PAOD) and the influence of different parameters on the primary success rate, the rate of complications and the long-term outcome. Patients and methods: We reviewed clinical and hemodynamic follow-up data of 166 consecutive patients treated with PTA in 1987 in our department. Results: PTA improved the clinical situation in 79.4% of patients with iliac lesions and in 88.3% of patients with femoro-popliteal lesions. The clinical stage and ankle brachial index (ABI) post-interventional could be improved significantly (each P < 0,001), the same results were observed at the end of follow-up (each P < 0,001). Major complications occurred in 11 patients (6.6%). The rate of primary clinical long-term success for suprainguinal lesions was 55% and 38% after 5 and 10 years (femoro-popliteal 44% and 33%), respectively, the corresponding data for secondary clinical long-term success were 63% and 56% (60% and 55%). Older age (P = 0,017) and lower ABI pre-interventional (P = 0,019) significantly deteriorated primary clinical long-term success for suprainguinal lesions, while no factor could be identified influencing the outcome of femoro-popliteal lesions significantly. Conclusion: Besides an acceptable success rate with a low rate of severe complications, our results demonstrate favourable long-term clinical results of PTA in patients with PAOD.

There are few long-term follow-up studies of parasuicides incorporating face-to-face interviews. To date no study has evaluated the prevalence of psychiatric morbidity at long-term follow-up of parasuicides using diagnostic rating scales, nor has any study examined parental bonding issues in this population. We attempted a prospective follow-up of 85 parasuicide cases an average of 8½ years later. Psychiatric morbidity, social functioning, and recollections of the parenting style of their parents were assessed using the Clinical Interview Schedule, the Social Maladjustment Scale, and the Parental Bonding Instrument, respectively. Thirty-nine persons in total were interviewed, 19 of whom were well and 20 of whom had psychiatric morbidity. Five had died during the follow-up period, 3 by suicide. Migration, refusals, and untraceability were common. Parasuicide was associated with parental overprotection during childhood. Long-term outcome is poor, especially among those who engaged in repeated parasuicides.
